FEED-WATER PU RIFIER.

SPECIFICATION forming part of Letters Patent N 0. 592,671, datedOctober'26, 1897.

Application filed April 23,1897.

To aZZ whom it may concern:

Be it known that I, EDWIN R. STILWELL, residing at Dayton, in the countyof Montgomery and State of Ohio, have invented certain new and usefulImprovements in Feed- Water Purifiers, of which the following is aspecification.

The object of my invention'is, first, to so construct the shelves of apurifier that they may be readily taken out and put into the heater,being readily removable through a manhole.

Another object of my invention is to make the shelves of cylindricalpipe-sections, thereby increasing the heating-surface, as well as makingthe sections light and easily detachable, renewable, and replaceable.

The features of my invention are more fully set forth in the descriptionof the accompanying drawings, making a part of this specification, inwhich Figure l is a central longitudinal vertical section. Fig. 2 is asection on line mm, Fig. 1. Fig. 3 is a sectional plan view of theshelves at one end thereof. Fig. lis a detailed View of thecam-clamp.Fig. 5 is a side view of Fig. 4.

A represents the shell of a horizontal purifier.- B represents pipes forsupplying live steam thereto. 1

D represents'the water-supply pipe.

0 represents the pipe through which heated water is carried to theboiler.

E represents a blow-off pipe.

H represents a series of brackets rigidly secured to the shell of thepurifier.

F represents longitudinal side plates secured to the brackets H andforming the side walls for the cylindrical-pipe-section shelves.

G represents a series of slats secured to the side plates F and bracketsH by means of the U-brackets I. Each shelf is composed of a series oftubes or pipes P,resting on the series of slats G. The upper shelfinclines forward toward the manhole J, and the next shelf underneath isprojected forward and inclined in the opposite direction; The sectionsof pipe composing the shelf are secured in position in the followingmanner:

(t represents a slat running across the front the $erial No. ()BBABO.(No model.)

1) represents an eccentric arm turning on the center 0. I

As shown in Fig. 1, the slat ais clamped at each end by the eccentric b,clamping the pipes between the removable slats ad at one end and thestationary slats a d at the other end. When the eccentric is turned overin position indicated in dotted lines, Fig. 1, the slat a is releasedand may be taken out and the pipes forming the shelf can be removedthrough the manhole. The second tier is held in like manner, but theslat d is elevated above the pipe sufficient to form a shelf and turnthe water backward across the second tier of shelves. There issufficient space between the ends of the tiers of pipe and the end ofthe heater to allow a person to work in for the purpose of removal andreplacing the pipe-shelves. The shelves could be made of semicylindricalsections and accomplish part of the object of my invention, but thepreferred form is the cylindrical.

By making the shelves of a series of pipesections arranged in intimatecontact with each other throughout their entire length severaladvantages are obtained. First, a large amount of heating-surface isobtained and very thin material may be employed; second, the lime ormagnesia which is deposited thereon begins at the abutting-point at thesides of the pipes, and as this fills up with deposit the water israised, bringing it against anew and clean surface of the pipe, whichconsequently takes up heat better than if the entire surface of theshelf was covered with a deposit. This will continue until the top orhighest portion of the pipe is covered with the deposit, when thesections can be removed and cleaned. I thus obtain a shelf which willnot require cleaning so often, and at the same time preserve the heatingefficiency by continually presenting a new uncovered surface of theshelf to the heating and depositing action. This is a very materialadvantage, as the heating efiiciency of the ordinary shelf constantlydeteriorates as the scale deposit increases, but with my pipe-shelf theheating efficiency is preserved a long time.

Another advantage obtained from the use of my pipe is that the scalereadily cleans oil? of the shelves and they are hence much less troubleto clean than the ordinary shelves.

K represents the overflow-box.

Having described my invention, I claim 1. A feed-water-purifier shelf,consisting of a plurality of cylindrical sections supportedlongitudinally side by side and in intimate contact with each otherthroughout their length, substantially as described.

2. In a feed-Water purifier, vertically-arranged brackets secured to theinside of the purifier, shelves supported by said brackets and eachconsisting of a plurality of cylindrical sections arrangedlongitudinally side by side and in intimate contact with each otherthroughout their length, and means for detachably clamping said sectionsin position on the brackets, substantially as described.

3. In combination with a feed-Water purifier, a series of bracketssecured to the inside of the purifier, shelves composed of pipe-sectionslaid upon said brackets, and clamp-lever engaging with a slat extendinglaterally across said purifier and abutting the ends of thepipe-sections, whereby the said pipe-sections may be clamped in positionby said lever, substantially as specified.

In testimony whereof I have hereunto set my hand.

EDWIN R. STILVELL.
